" L Y-HANGE f To all whom it may concern: x 1

Be it known that we, RICHARD T. T01)- HUNTER, HARRY- A. DUKE, citizens of the United States and ALEXANDER Woons, subject ofthe Barnesboro, in the county of Cambria and State of- Pennsylvania, have invented certain new and useful Improvements in TrolleyHangers, of whichthe following is a specification, reference being had therein to the accompanying drawings- This invention. relates to a trolley hanger, and has for its object theconstruction of a trolley hanger that is comparatively simple, yet eflicient in operation and durable in construction.

With this and other objects in view our invention comprises certain novel combinationsand arrangements of parts as will be hereinafter specifically described, illustrated in the accompanying drawing, and more particularly pointed out in the appended claim.

In the drawings:

Figure 1 is a view in side elevation of a trolley hanger constructed in accordance with the present invention, while Fig. 2 is an end View of the hanger, showing the jaws in their outward extended position, and the trolley wire displaced from be- .tween the jaws.

Fig. 3 is a sectlonal view taken on line 33 Fig. 1.

Fig. 4 is a top plan view of the hanger shown in Fig. 1.

Fig. 5 is a view in side elevation, looking at the interior of the auxiliary jaw, while Fig. 6 is a similar view of the primary aw. 1 Referring to the drawings by numerals, 1 designates the primary jaw, and 2 the auxiliary jaw. The primary jaw comprises a body having a longitudinal extending groove 3, an inwardly extending bead or rib 4, and an outwardly curved or beveled por tion 5. Integral with the grooved portion 3 is an auxiliary grooved portion 3 (Fig. 6), and integral with this grooved portion 3 are alined, integral sleeves 6, 6.

A vertically extending sleeve portion 7 is,

similar in construction to the sleeve portion 7 on auxiliary jaw 2 (Fig. 5). A. stub pin 8 extends beyond theinner face of the rib 4 (Fig. 3) for the purpose hereinafter specified.

I On' the. auxiliary 2, in alinement, are a pair of auxiliary sleeves 61 that," 1 when the two aws are placedtogether, as

shown in Fig. 3, register in alinement, so

that ashaft or nail9 can be run through these sleeves, aswell as the anchor .bolt 10, holding all of 'theparts of our hangerin w an assembled position. A

and isadapted to be threaded intothe coni- 1 1 of the sleeve portions 7 of the jaws and by rotating the attaching member 12 with respect to the anchor bolt 10, the jaws 1 and 2 can be closed more tightly upon their ,The anchor bolt 10 is-externally threaded, Y

pivot, constituted by the fastening member 9' 9, or can be loosened, as desired, to control the pressure exerted upon the trolley-wire 13.v

The trolley-wire 13 is placed between the removable metal trolley engaging plates 14, 14, which plates fit the portions 3 and 5' of the jaws; these plates are provided with channels 15 that permit one or more trolleywires 13 to be supported upon our hanger, or if one edge of the plates become worn, the plates can be reversed in the hanger, exposing a non-worn edge, if desired. The pins 8 project at their innerends intoapertures 16 formed in the plates 14; these apertures 16 being formed between the channels 15, Fig. 3. These pins 8 provide temporary means for holding the plates 14 between the jaws until the trolley-attaching member 12 is screwed upon the anchor bolt 10 sufficiently to cause the jaws 1 and 2 to tightly clamp the trolley-wire 13 through the medium of the plates'14. By unscrewing the attaching member 12, moving the same outward or upward upon the anchor bolt 10 (Fig. 2) the jaws may be thrown apart and the trolley-wires 13 permitted to be dropped out of the jaws asshown. V

The alined sleeves 6 fit against the outer ends of the sleeves 6" on the auxiliary jaw, whereas the sleeves 6 fit against the inner ends of the sleeves 6 on the primary jaw when the parts are in their assembled position, then the anchor bolt is placed down in between the jaws until the apertures formed therein near its lower end register whereuponthe interiorly-threaded attaching member 12 can be screwed upon the anchor bolt, closing the lower ends of the I jaws together upon the trolley-plates 14: and

the trolley-wire 13. It will be noted that the action of the trolley attaching member 7 threaded upon the anchor bolt 10 is that of a wedge for wedging the jaws together at their trolley-Wire supportingends." The trolley hanger here1n described can be attached to a support. (not'shown) in any suitable manner.

What We'olaim is: a In a device of the class described, the

combination, of a pair of elongated jaws,

each jaw provided'with a' pair of alined sleeves and with a longitudinally extending groove and with a beveled lower-portion, each-jaw being provided with a longitudinally extending rib between the groove and the beveled lower portion, each jaw being provided with a pin extending inwardly upon said rib, a pair of channel trolley-sup porting plates upon said pins and resting in said grooves and beveled portions, each j aw being provided with a vertical sleeve 'portion, said vertical sleeve portion provided with conical faces, an externally-threaded anchor bolt provided with an aperture near 7 its lower end positioned between'said jaws 30"" and between said sleeves of thejaws and having its aperture'registering with the ap-v ertures of the alinedsleeves, a detachable fastening member extending through the apertureof the alined sleeves and the aper- 35 ture of the anchor bolt, and'an attaching member threaded upon said anchor bolt and having a conical portion positioned in the vertical sleeve portions of the jaws and bearing against the conical faces thereof, 1o
